Building envelope such as external walls are still constructed from poor materials which results in higher heating and cooling loads thereby raising energy bills. Improving building efficiency with advanced technologies is being sought. In this context, a numerical study was conducted to solve the coupled heat transfers through standard wall structure used Libyan residential buildings. Differen...

Global warming potential is one of the most important life cycle assessment indicator, which shows how much heat a greenhouse gas traps in atmosphere relative to CO2. In this study, we calculated global highly insulated building construction detail residential nearly-zero energy based on numerical simulations. To calculate loss constructions, necessary for estimating operational demand use phas...

Polarization and Depolarization Current (PDC) testing is a non-destructive dielectric testing method to determine the conductivity of insulations. It is one of the dielectric d iagnostic techniques based on time domain measurement. PDC measurement technique has gained immense popularity due to its ability to assess the condition of HV insulation. PDC measurement can provide information about th...

The objectives of the present study were to evaluate the effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus crossbred bulls. In one experiment, B. indicus bulls (n=12) were allocated to control and whole-scrotum insulation groups, while in a second experiment, crossbred bulls (n=21) were allocated into control...

The objective of this paper is to compare the thermal behavior a light frame timber wall by measuring 15 test samples with various insulation materials versus theoretical simulation use software. This work establishes variance between two different methods measure transmittance coefficient walls. It verified that mean percentage alteration 4.25%. Furthermore, approach proved software, additiona...

Conventional dielectric response measurement techniques, for instance, recovery voltage measurement (RVM), frequency domain spectroscopy (FDS) and polarization–depolarization current (PDC) are effective nondestructive insulation monitoring techniques for oil-impregnated power transformers. Previous studies have focused mainly on some single type of dielectric measurement method. However, the co...

A 57-year-old man was admitted to our hospital for endoscopic submucosal dissection (ESD) for early gastric cancer. The lesion was located at the anterior wall of the proximal antrum to the lower body. After incision [1,2], about 350 cc of distilled water was infused into the stomach (●" Fig.1). The weight of the water changed the shape of the stomach, so that the anterior wall rotated from the...

In the present work, the exergy analysis and economic study of 3 different samples of threecomponent mixtures have been investigated (ESI>1, ESI≈1, and ESI<1). The feed mixture has been tested under three different compositions (low, equal, and high contents of the intermediate component). A quantitative comparison between simple and complex configurations, considering thermally coupled, thermo...
